Security boundaries of an optical power limiter for protecting quantum key distribution systems
Qingquan Peng, Binwu Gao, Konstantin Zaitsev +7
Unauthorized light injection has always been a vital threat to the practical security of a quantum key distribution (QKD) system. An optical power limiter (OPL) based on the thermo…
